The ARRI RIA-1 Radio Interface Adapter functions as the hub of your Hi-5 control system, supporting ARRI's interchangeable RF-EIMP, RF-2400, and RF-900 radio modules. Use the RIA-1 for remote focus, iris, and/or zoom control and camera run/stop and tally functions.

The RF-EMIP Radio Module 2400 MHz DSSS (Direct-Sequence Spread Spectrum) from ARRI is an exchangeable radio module designed for use with the Hi-5 lens control hand unit and the Radio Interface Adapter RIA-1. This module offers point-to-multipoint communication for connecting up to three hand units with one camera.

Use the Cable CAM (7p) - RS (1') from ARRI to connect an ARRI cforce RF lens motor, cmotion cPRO lens motor, or cmotion cPRO camin to your Alexa or Amira camera. This cable enables the camera's RUN/STOP, and tally functions when used with an ARRI or cmotion cPRO electronic-control hand unit.

This 1.5ft long ARRI LBUS Cable connects compatible LBUS devices, carrying power and control signals between devices. The 4-pin LEMO connectors are straight through, and the cable is designed to withstand the rigors of the production day. The connector ends feature shrink tubing where the cable enters the connector. This strengthens the attachment and helps keep dust out of the connector interior.
